Juniper QSFP-100GBASE-SR4 100G QSFP28 Module | Ethernet, SR4, Enterprise

Keep 100 GbE fabrics moving with the Juniper QSFP-100GBASE-SR4 QSFP28 pluggable module. Designed for Ethernet-only operation, it supports short-reach multimode deployments where switch density, link consistency, and straightforward integration are essential. The SR4 optical design is well suited to data center uplinks, leaf-spine architectures, and aggregation layers that depend on high-bandwidth links without moving to longer-reach, higher-cost optics. This module is a practical fit when you need to preserve port density while scaling throughput. QSFP28 packaging keeps the footprint compact, helping infrastructure teams maintain clean cabling and efficient use of switch ports. For environments standardizing on 100 GbE over multimode fiber, it offers a focused path to performance without paying for reach you do not need. Choose this module when the priority is dependable 100 GbE transport in tightly controlled distances and Ethernet-centric networks. It is a strong match for teams that value vendor-aligned optics, predictable deployment behavior, and the operational simplicity of a purpose-built SR4 transceiver.
